JavaScript(JS) string method - fromcharcode

The fromCharCode() method is a static method in JavaScript's String object, which is used to create a string from a sequence of Unicode values.

Here's the syntax for the fromCharCode() method:

String.fromCharCode(num1, num2, ..., numN)

Here, num1, num2,..., numN are the Unicode values of the characters that you want to include in the resulting string.

For example, let's say you have a series of Unicode values representing the characters "H", "e", "l", "l", "o":

let unicodeVals = [72, 101, 108, 108, 111];

You can use the fromCharCode() method to convert these values into a string:

let str = String.fromCharCode(...unicodeVals);
console.log(str); // Output: "Hello"

The spread operator ... is used to pass the array of Unicode values as individual arguments to the fromCharCode() method.

Note that the fromCharCode() method is a static method, which means that it is called on the String object itself, rather than on an instance of a string.
